Starting with L-tartaric acid the chiral 3,4-disubstituted pyrrolidine analogue sulfonamide derivatives were prepared. These compounds were examined for anti-bacterial and anti-fungal activity. Further the docking studies were carried out for the model compounds from each series against β-glucosidase and the results found are moderate. The structure–activity relationships are also briefly discu...

C2-symmetric vicinal diamines 3b–f, derived from L-tartaric acid, with increasingly bulky terminal ether functionalities were prepared using two distinct sequences. Diamines 3b,c were obtained from the corresponding vicinal diols 4b,c, while diamines 3d–f were generated from dihydroxydiazide 7 via deprotection–reprotection strategies. © 1999 Elsevier Science Ltd.

4 Williamson (Physic. Rev., 21, 110, 1923), using a tartaric acid solution composed of 64 parts of water to 1 of saturated solution in an absorption cell 3.2 cm. in length, found no transmission below 2450 A. Using a 3 mm. layer of 1.7% solution we found with a quartz spectrograph no transmission below 2340 A. Moreover, through even a 0.17% solution, 'we obtained no unsensitized ozone formation...

In order to establish prerequisite conditions for hyphenation of inductively coupled plasma– atomic emission spectrometry with liquid chromatography, the effects on plasma signal by loading of low concentrated solutions of tartaric, citric and dipicolinic acid were studied. The intensities of Mn, Li, Mg, Cd and Cu lines were observed in axial and radial signal collection mode. Influences of dif...

perilla frutescens is an annual herb of the mint family native to east asia. polyphenols present in perilla have various structural varieties with large diversity of biological activities. it is direct influence the quality of perilla plant and their potential functions. some of these products have been studied and proven to be effective source of phenolic antioxidants. the aqueous extract cont...

BACKGROUND Methanol has become an alternative fuel for gasoline, which is facing a rapidly rising world demand with a limited oil supply. Methanol-gasoline has been used in China, but phase stability and vapor lock still need to be resolved in methanol-gasoline applications. In this paper, a series of tartaric esters were synthesized and used as phase stabilizers and saturation vapor pressure d...

In an earlier study of the effect of culture of excised tobacco leaves in darkness in solutions of a number of common organic acids (1)) it was noted that the behavior of the malic and citric acids in leaves cultured in (+)tartrate differed little if at all from that observed in the control samples cultured in solutions of inorganic salts. However, the so called “unknown acid” fraction, i.e. th...
